New to Chao? Well, i can help you
If you don't know what chao is I think I can tell you guys about them. Chao are cute and adorable and small little creature that you can interact with them and they love a garden called chao garden. First you'll see two eggs at the garden they are colored eggs and when those eggs hatch they are baby chao but when there born they are light blue and yellow and they can't walk yet you have to give them animals (you have to give them rabbits to make them walk) Then your chao will learn how to walk. Chao can evolve In a cocoon and If you hear two different jingles that means that your chao evolved, one good one and one sort of a bad one. They look like this.
If you pet your chao with a hero character (Sonic, Tails, and Knuckles) your chao will evolve into a Hero Chao. Hero Chao are (A.K.A. Baby Angels In my opinion) and are one of the good guys. To get one you have to pet your chao until you see it turn into white and blue color. They look like this.
If you pet your chao with a dark character (Shadow, Eggman, Rouge) your chao will evolve into a Dark Chao. Dark Chao are (A.K.A. Baby Devils In my opinion) and are one of the bad guys. To get one you have to pet your chao until you see it turn black and red. They look like this.
